ULTRAROOF380 OVERVIEW

Key performance criteria/simplifi ed rules• The product can be designed with window frames to all elevations - no support posts.

• If bi-folding doors are to be used they MUST be bottom supported NOT top hung.

• The standard soffi t projects approx 40mm beyond the external face of the window frame - box eaves beam is approx

380mm front to back depth.

• Pitch range - minimum is 12.5° on lean to and 15° on duo pitch - maximum pitch is 40°.

• Pitch must be equal to all sides - on 3/5 bay Victorians facet sizes must be equal size / angle.

• System ‘U’ values - with the 190mm Unidek Aero panels is 0.16W/m2°C.

• Rectangular glass panels can be integrated to maintain light into any adjacent room. Alternatively, add one of 4 Velux

roof windows/sizes.

• Everything is pre-fabricated in our highly effi cient factory to ensure rapid one day fi t on site.

• On a 4m x 4m Georgian, the system weight is 38kg/M² including plasterboard (12kg/m2 polycarbonate roof and 30kgM²

for a glass roof).

U-DesignU-Design is a piece of design and confi guration software that exclusively specifi es UltraRoof380. As

well as visualising and pricing, upon entry of the customer’s postcode it checks the wind and snow

loads at the exact location to ensure UltraRoof380 complies with Building Regulations.

IT IS STRONGLY RECOMMENDED THAT THE ULTRAROOF380 INSTALLATION GUIDE IS READ AT THE SAME TIME AS THIS DOCUMENT.

Product defi nitionUltraRoof380 is a solid roof, perfect for the speedy replacement of tired conservatory roofs. It is a packaged solution, off site manufactured for rapid assembly and compliant with relevant Building Regulations. UltraRoof380 is classed as a ‘warm roof’ and gives a vaulted/loft type ceiling. There are three major elements to UltraRoof380;

A patented box eaves beam, fi lled with

EPS beads as used in cavity insulation

- that forms the soffi t structure -

approx 380mm front to back depth.

A hidden structural aluminium

framework for hips, ridge and starter

bars.

Mechanically fi xed Kingspan Unidek

Aero Structural Insulated Roof Panels

are attached to the box eaves and

structural framework.

The roof comes with the counter battens

already fi xed. Tongue and grooved 12mm

OSB is then fi xed before a self adhesive,

high performance water proofi ng layer is laid.

UltraTile engineered copolymer interlocking

tiles sheet (12 slates per sheet) are then laid

across the roof slope.

HANDY CHECKLIST FOR:

SELLING AND DESIGNING THE PERFECT ULTRAROOF 380

1. Choose the preferred roof shape (Georgian, Lean To, Victorian, Gable etc). Although the shape of most

Victotrian Conservatories can be replicated like for like, if the facets are uneven the Tudor Roof must be used.

See pages 11 and 74.

2. Ask the customer precisely where they would prefer the glass in the roof. UltraRoofs full height rectangular

glass panels are the most cost eff ective way to add glass, but are only available when connected to the ridge.

Velux also can be used and located in most places on the roof. Refer to pages 8, 29 - 42.

3. Some box gutters may need internal beam support (See pages 34-35). If the customer wishes to change the

box gutter types to avoid internal support this may restrict the placement of the glass. On some roofs there

may be a trade off between internal support and glass placement. Read pages 47-55 and discuss this with the

customer.

4. When a box beam is next to a host wall and a tapered gutter is used it does not require supporting (if under 4m

clear span). All 265 boxgutters require supporting under the beam. Roof glazing choice must be considered

when choosing boxgutter type. See pages 34-35 and 47-55.

5. The box beam has a maximum length of 7m but beams can be jointed. Where the joints are located due to the

supports required see pages 6 and 67-72.

6. The beam cannot run unsupported over 4M. Avoid building bi-fold doors over 4M spans into the design to

avoid the need for extra structural support. See pages 47-55.

7. Building Regulation compliance is required for SOLID roof conversions and new build extensions. See page 19.

8. Use the guide to explain how the soffi t will look to the customer. See pages 26 and 62.

Soffi ts over the window frames are available in 40mm and 151.5mm. Refer to page 63 and 67 to identify the right soffi t on

masonry. Please note, the 151.5mm sofi t is the only option compatible with Loggia Super Insulated Columns.

10. Obtain the POSTCODE so that wind and snow loads can be checked. If you suspect these loads may be high

refer to pages 43-46 to understand maximum potential roof sizes available.

11. There are many choices of fi nish to the UltraRoof380, much more than tiles. Ensure you have decisions from

the homeowner on everything in the design. See pages 12-16.

12. Agree the roof pitch with the customer. Every roof must be pitched in full degrees (e.g. not 25.5°), duo pitches

range from 15°- 40° and Lean To’s start at 13°-40°. The only exception to this rule is the lowest Lean To

possible which is 12.5°

13. Design the lighting layout with the customer. LED spotlights can be placed within the internal pelmet or added

using a board at the ridge. Pendant lights can look particularly striking from the ridge of the new roof.

See page 16.

Always consult Ultraframe if there is something you are uncertain about, please call Ultraframe’s technical helpline on 01200 452 918 or visit [email protected]

STEP 1 - LAYOUT - THINGS TO CONSIDER

Any rectangular fl oor plan can be built, standard 3 & 5 bay victorians but NO P-shapes or T-shapes can currently be replaced. Valleys will soon be available. Stretch Victorian replacement roofs can be accommodated (see page 11).

4 STAGE SALES AND DESIGN PROCESS

The maximum length of UltraRoof380 beams are 7m but 2 can be joined together, however you will need a post or column where the beams join. Ensure the joint positioning is aligned with door or window frames Refer to page 67-68 for detailed information.

Loggia columns can easily be integrated with UltraRoof380. An extended soffi t must be used with Loggia columns. See page 73.

UltraRoof380 has 2 soffi t depths 40mm and 151.5mm, see soffi ts shown on frames across. Discuss with the homeowner re depth of soffi t required on brick work and frames. See page 63 and 64.

Tudor. See page 75 for details.

STEP 3 - ROOF STYLE - SHAPE


Out of square.

UltraRoof380 can accommodate out of square existing buildings due to the wide nature of the beam. The soffi t line will

taper on both the inside and outside but the roof will remain square. The 151.5mm extended soffi t MUST be used in

this situation.

In extreme cases it might be better to recommend a re-build to make it square. See example below.

Existing Victorian shaped

roofs can be replaced with

a Georgian shape with a

cantilever overhang which

could include a lighting

feature. This is particularly

useful if the facets are

uneven as UltraRoof380 can

currently only accommodate

even facets.

The deviation that is possible on standard 40mm soffi t without on site modifi cations to parts is 10mm.

BUILDING REGULATIONS

ENGLAND & WALES - REPLACEMENT ROOFSBuilding regulations for replacement roof projects can be applied for EITHER through the Local Authority Building Control Department OR through a private sector Approved Building Control Inspector.

The design details for UltraRoof380 has been registered with JHAI, an Approved Building Control Inspector who have audited the UltraRoof380 manufacturing process. JHAI’s inspectors provide a consistent and informed service when applications are made to them, typically with only one inspection visit arranged directly with the householder. For more details visit www.UR380info.com

ENGLAND & WALES - NEW BUILDSBuilding regulations for new build projects can be applied for EITHER through the Local Authority Building Control Department OR through a private sector Approved Building Control Inspector.

JHAI off er building control service for new build projects, with up to six visits to site if required depending on the complexity of the project. Please visit www.UR380info.com to download details of JHAI’s costs and service.

SCOTLANDA building warrant is required for all roof replacement and extensions in Scotland. An SER (Structural Engineers Report) is typically required as part of the warrant application. Please consult Ultraframe if you need advice on structural engineers who have experience with UltraRoof380.

Building regulations for replacement conservatory roofs are ambiguous, however we recommend that retailers apply for building regulation approval because the lack of a completion certifi cate can become a costly issue when the property is sold. UltraRoof380 meets building regulation requirements. To ensure the design is fi t for purpose, please provide the postcode so that wind and snow are applied correctly to the design. In addition to the quotation Ultraframe can provide a thermal report to enable SAP calculations to support the building regulation application.

ASSESSING THE EXISTING CONSERVATORY

The primary fi xing method of the roof is at the house wall and through the head of the window frames and into the beam. At the corners fi xing is made through the existing frames into the OSB corner sheves (which are supplied) and into the beam. When fi tting UltraRoof380 onto the existing frames, then the side frames may need de-glazing to allow fi xing of box eaves beam. Use bay pole fi xings at 450 centres and no more than 200mm from each eaves end / corner.

Changing the roof on a previously exempt conservatory from glazing to solid panels means that you have changed the status of the structure.

The new roof is seen as an improvement and MUST comply with parts of the Building Regulations (this assumes the doors separating the house and conservatory are retained). There is a caveat – the replacement roof should not make the condition of the existing structure worse – this relates to the ability of the existing side frames and foundations to carry the additional loads imposed by the solid roof. It is necessary to undertake some structural checks that MAY lead to additional site works.

Adequate support from the existing structure is required in three main areas by:1. Window frames.2. Mullions/corner posts.3. Foundations.

Unreinforced PVC Frames. If at survey stage there is no

reinforcement within the PVC frames it may be necessary to

replace the corner posts. The dead load of UltraRoof380 is

38Kg/m2 plus the snow load which as a minimum is typically

60kg/m2. On a 5m x 5m Georgian roof for example, the load

is 2803Kg which translates to a maximum loading at each

corner of 7kN.

Using the table to the right it can be seen that an aluminium

corner post of 50mm square hollow section with a 2mm

wall will be adequate - generally corner posts will be larger

than this. At survey stage it may be diffi cult to confi rm the

presence of the aluminium inside the PVC sleeve until the roof

is removed. Assuming new frames are not being installed, it

may be advisable to send with the fi tters some spare corner

posts to swap with the existing.

ASSESSING THE EXISTING CONSERVATORY - GUIDELINES

Remediation work (mini piling etc.) can be undertaken cost eff ectively – Ultraframe recommends QUICKBASE 0845 644 0000 if you wish to pursue this option.

- There is an inadequate depth of foundation. The strip foundation MUST be a minimum of 450mm and the concrete strip a minimum of 150mm thick.

- There is visible movement between the house wall and the conservatory dwarf wall or cracks in the dwarf wall - this is a clear indication the foundations are not adequate and also require remedial work.

IF IN DOUBT ABOUT STRUCTURAL COMPLIANCE, PLEASE CONSULT LABC, Jhai OR A STRUCTURAL ENGINEER.

Mullion as a wind post:- the size of the mullion depends on the height of the frame. With full height frames (2100mm) the mullion needs to be the full front to back depth of the window frame and at least 20mm wide.

Adding mullions to existing frames is not really viable – this option should be considered if the consumer has requested new frames/doors. Should the PVC frames be replaced, the insertion of suitable mullions can obviate the need for reinforcement in the frames (as far as structural reasons are concerned) – when using mullions, always place a 20mm washer behind the head of the screw to spread fi xing loads.

MULLIONS

An aluminium mullion performs a number of functions, namely; - acting as a wind post to prevent defl ection of the frames by wind pressure - to support the roof’s eaves beam - to assist with the connection of the side frames.

FOUNDATIONS

As everyone knows and appreciates, foundation design greatly depends on local ground conditions and advice should be sought from local LABC or an Approved Inspector like Ultraframe’s partner jhai. However there are some rules which are absolute and therefore if the proposed conservatory falls outside this it may be necessary to underpin the existing or remove the existing base and start again. Take up the old foundations if;

INTERNAL FRAMES OVERHANG IS SET WHEN BOX EAVES BEAM SAT ON

STANDARD SOFFIT 40mm 70mm frames

EXTENDED SOFFIT 151.5mm 70mm frames

1 UltraRoof380 must be made square, with EQUAL angles (i.e: 90, 135 or 150 degree angles), EQUAL facet sizes and

EQUAL pitch - Out of square can be accommodated or Tudor used. See pages 75-76.

2 Lean-To’s with hipped end(s) must have SAME pitch front and side(s).

3 Every roof must be pitched in full degrees (e.g. not 25.5°), duo pitches range from 15°- 40° and Lean-To’s start at 12.5°,

otherwise 13-40 in one degree increments available in full degree increments.

4 On replacement roof only jobs existing internal frame angles may vary. This will result in varying internal/external

soffi t depth variations being visible. If extreme, replacing the frames would be recommended. If existing basework/

brickwork angles are out, the fi tting of a deeper external cill may hide discrepancies.

5 Externally, UltraRoof380 with “Standard soffi t” is 180mm (90mm each side) wider than Classic roof. Greater care is

needed when working close to the boundary line. UltraRoof380, coincidentally, is the same width as Classic roof with

Cornice .i.e: 242mm from internal frame to outer edge of gutter.

6 Externally, Ultraroof380 with “Standard soffi t” sits 53mm higher on slope/pitch than Classic roof. This should not

aff ect an existing lead fl ashing line if going to be re-used.

7 Externally, UltraRoof380 overall roof height (stated on roof confi rmation) is measured from underside of box eaves

beam (head of frame, unless packed off ) to top of external ridge top capping. Allow for standard ridge fl ashing detail

above this.

8 Externally, if fi tting “Extended soffi t” the roof sits 100mm higher on slope/pitch than Classic. This could interfere with

existing fl ashing detail. Critically more important if a cavity tray is installed. Therefore, if cavity trays are installed,

standard soffi t overhang would be better suited.

9 Internally, using “Standard soffi t” detail: The box eaves beam (when plastered) stands 321.5mm in from internal

frame. ENSURE this does not cut across an internal patio door/window opening on the rear host wall. Using “Extended

soffi t” which stands only 210mm in from internal frame may help in this situation. Reducing the opening width and

replacing with narrower doors may be an alternative solution. See page 26.

10 Internally, each box beam contains a built-in cabling channel, the centre of which is set 123mm in from the internal

face of the steel box beam. See page 26.

ULTRAROOF380 INFORMATION

ULTRAROOF380 SURVEYING GUIDELINES

UltraRoof380, light weight solid roofi ng diff ers from Ultraframe Classic conservatory roofi ng in that, it off ers a traditional overhanging soffi t area beyond the external frame face. Initial site survey is no diff erent in that great care must be taken in examining the existing host wall for being fl at (ie: bulges or bowing from left to right) and vertically plumb (ie: leaning forwards or backwards). If any of the above issues are detected then this must be allowed for in your fi nal sizes.

If replacing a conservatory roof on 60mm frames with Standard soffi t, the soffi t overhang increases to 50mm. If installing on 100mm frames, the Standard soffi t overhang would reduce to 10mm.

ULTRAROOF380 IS WORKED FROM INTERNAL FRAME SIZES.

Check the House WallThe box beam is large and should not be cut on site. Tiles are pre-cut to minimise work on site. As a result adjustments in size due to variations in the house wall are best made at survey stage.Please check the house wall to establish whether it is plumb. Adjusting the projection dimension before manufacture will ensure your design will fi t. Please advise your installers that you have made this adjustment to avoid confusion on site.

Replacement Roofs.If the roof is being replaced adjustments for out of plumb dimensions should be taken at eaves level, reducing the projection if the wall leans forward or adding to the projection if the wall leans back.

Diagram BDiagram A

This information applies to both replacement and new build projects. Please read this guide before commencing your survey.

EXAMINING THE HOST WALL

New Build.If the house wall leans forward: when the UltraRoof380 half ridge (shown) butts to the house wall the whole conservatory will be pushed forward of the basework, resulting in excessive overhang at the front. You would benefi t by reducing the projection in this case to . See Diagram A.

If the house wall leans backwards: then the roof projection dimension should be taken from the top of the dwarf wall and a suitable packer will need to be inserted between the end of the ridge and house wall when installing. See diagram B.

SPECIFIERS

– USEFUL POINTS TO REMEMBER WHEN ORDERING ULTRAROOF 380

1. A Building Regulation application form must always be submitted to the relevant Local Authority or private sector

building control.

2. Postcodes should always be included with your order so that the structural design guide within the software will

ensure the snow and wind loads are correct.

3. With a standard soffi t UltraRoof380 is 90mm wider than a standard conservatory roof on both sides and 205mm

wider when the extended soffi t is used. Include all WALL heights and distances to boundary lines in fl oor plans

and elevations.

4. UltraRoof380’s aluminium ridge and hips caps are generally preferred vs replica tile ridge caps as they are

considered to look better and are fi tted much faster. Both options are available, see page 12 for restrictions.

5. All new window frames and cills should be fully reinforced to support UltraRoof380. A maximum frame length of

2.5m is allowed before structural couplings are required.

6. UltraRoof380’s unique full height glass panels are the most cost eff ective way to install glazed panels and are

consumer preferred due to their size. There are however some limitations to the glazing options off ered.

See pages 29 and 35.

• Rectangular glass units can NOT be positioned on roof slope down to tapered box gutter.

• 550mm wide Velux roof windows only. Can be installed to tapered or 265mm box gutter.

• Integrated glazing. Only rectangular glass units up to 1,000mm wide at 90° to the ridge are permitted.

7. The UltraRoof380 box beam requires structural support in certain situations e.g. over 4M spans and when a

265mm box gutter is used. The structural support options off er a design choice for homeowners. Ensure that the

options have been agreed with the homeowner in advance. Refer to pages 47-56.

8. During the initial stages of installation the box beam will need to be supported. Ensure timber support props or

acro props will be available on site, refer to installation guide.

9. There are two box gutter options; standard 265mm or tapered. Tapered box gutters can only be used when box

beam or roof panels directly abut host wall. Refer to pages 9 and 34-35..

10. UltraRoof380 comes in three shades of authentic tiles and you can order a range of colours for Fascia board,

Barge board, Gable infi l & Guttering etc. See pages 13-15 for options

11. Several items are not supplied by Ultraframe as they are easier and cheaper to source locally.

These are:-

• Velux roof windows and EDL fl ashing kits (the roof arrives prepared for Velux)

• Anchor or Masonry fi xng bolts to host wall

• Internal 25mm x 50mm timber plastering battens.

• 12.5 foiled backed plaster board and skimming beads.

• LED (fi re resistant) lighting.

• Structural support

One of UltraRoof380’s features is the ability to have fully glazed panels that span right from the ridge to the edge of the roof, allowing great amounts of light to enter a room. These glass panels can be arranged in all manner of ways and confi gurations to give the desired result for design of the roof.

An alternative to fully glazed panels on UltraRoof is the option of Velux roof windows. These can be used to overcome issues in the design such as tapered box gutters or just as an alternative to a fully glazed panel. To cater for a Velux, UltraRoof uses a cassette in place of a panel to enable it to be fi tted into a desired position. The following shows the rules around cassette positions on an UltraRoof380.

Some box gutters may need internal beam support (See page 35). If the customer wishes to change the box gutter types to

avoid internal support this may restrict the placement of the glass. On some roofs there may be a trade off between internal

support and glass placement. Please read pages 47-55 and discuss this with the customer.

CHOOSING APPROPRIATE BOX GUTTER AND SUPPORT

Standard boxbeam needs structural support. When a 265mm box gutter is used if the length of the boxgutter exceeds 4m and additional support is required. See pages 47-56.

A

STANDARD BOX GUTTER

When a tapered box gutter is used the box beam is always supported by a wall mounted angle bracket that runs along the length of the beam. This instance does not require structural support.

B

STANDARD TAPERED BOX GUTTER

The box beam is always supported by the window frame that runs along the length of the beam. This instance does not require structural support. The beam requires support every 4m. In addition to the frames. This support may come from either a frame coupler or corner post.

C

BOX BEAM ON WINDOW FRAME

The box beam is always supported by the brick work that runs along the length of the beam or window frames in openings in the brickwork. This instance does not require structural support.

D

Turn to page 43, the correct page for the style of extension (in this case Georgian) and use the chart that shows the pitch range (defi ned as 25° for this project) .As the project is defi ned as 4m x 4m, look up the loading for this size which shows UltraRoof380 can accept a load of 1.5kN/m2 from wind and 0.89kN/m2 from snow.

Now check how high above sea level the location is (Google search or try www.maps-streetview.com) – in this case it’s 76m elevation above the sea level. As outlined in the worked example in red above, the location is in a small town (not the country).

Use fi gure 1, page 45 to check the wind speed at the location (in this case its 23 m/s which translates on table 1 to 0.68 kN/m²). From fi gure 2, page 46 check the snow load at the location (which is 0.6kN/m²).

Both fi gures at the actual site are within the design parameters of the UltraRoof380 system, so it is OK to proceed with the project with no amendments.

And fi nally, to determine the number and size of Velux roof windows that can fi t into this extension, turn to pages 37-39 for front elevation and side elevation to look up the vent opening sizes that can be confi gured into each elevation.

The only accurate way to specify UltraRoof380 is using U-Design software.Either use a licensed copy of the software or send a sketch to Ultraframe or one of its approved trade intermediaries / distributers, where the information will be input on your behalf.

If you are unable to achieve the desired size for your UltraRoof380 project please contact Ultraframe’s Technical Support Team for advice on 01200 452 918

Worked Example

A 4m x 4m* Georgian conservatory at 25 degree is being re-roofed at the rear of a semi-detached property in the small market town of Clitheroe. The homeowner wants to know if they can have Velux roof windows and what size and how many.

STRUCTURAL SPECIFICATION GUIDELINES

The size limitation for UltraRoof380 is limited by the projects geographic location.The location of each project will determine the imposed loads on the fi nished structure (both wind and snow loadings will have an impact). The size of these loads can be obtained from U-design software as the roof is being specifi ed. U-design uses historic weather datafi les which from a postcode can provide both wind and snow loadings. If you do not have access to U-design the maps will help guide you to the approximate loadings. This will not give you exact values but ones likely to be the worst case for your location.

IMPORTANT - NOTE 1The installer is responsible for ensuring that where UltraRoof380 is supported by means such as timber frame walls, the structure provides enough lateral support and resistance to wind uplift. Further guidance can be obtained through this guides technical documentation. Ultraframe cannot be responsible for the structural adequacy of any existing building work used as part of an overall conversion. While assistance is provided, ultimate responsibility to secure Building Regulations lies with the retail installer.

IF IN DOUBT ABOUT STRUCTURAL COMPLIANCE, PLEASE CONSULT LABC, JHAI OR A STRUCTURAL ENGINEER

IMPORTANT - NOTE 2This guide is intended to provide indicative information and to help you understand the design principles and applicable loadings. U-Design is the fi nal arbiter on price and specifi cation decisions.

IMPORTANT - NOTE 3The UltraRoof380 components have been designed and manufactured to meet the specifi cation of each individual job. Any signifi cant on site modifi cations particularly relating to the repositioning of any structural members will invalidate the product’s warranty and compromise the structure’s integrity.

Structural support is a vital consideration when designing the UltraRoof 380. This document highlights the many variations and options available when adding structural support and crucially determining when and how it should be used. Support is needed in order to create roofs of various sizes, allow for various obstacles/intrusions and to fi t into its designed space eff ectively.

If there is nothing in this document that relates to your situation then please contact our team and we can assist in working out a solution.

A BOX BEAM DOES NOT CONTACT THE HOST WALL

When a beam is not supported by the host wall via a bracket of any kind, then the beam needs additional structural support.

In this example, the box beam does not interact with the host wall and needs structural support from below.

UltraRoof has a series of styles and shapes that have to be supported by the box beam which in turn must be supported by window frames or connections to the host wall. When a beam is in a position where it can no longer support itself, extra structural support is needed.

The instances where beams need structural support are as follows:

When a tapered box gutter is used, the standard support for the beam is an angle bracket that is fi xed to the house wall running along the length of the beam.

INTRUSIONS

In some cases a roof may have to accommodate intrusions into the footprint of the roof, these are such things as chimney breasts. In this situation, the panel is adapted around the intrusion and a tapered box gutter is used. This creates many confi gurations of box gutters that allow water to drain away eff ectively.

INTRUSION TAPERED BOX GUTTER

The panel is always supported by a wall mounted angle bracket that runs along the length of the intrusion. This instance does not require any additional structural support.

MINIMUM INTRUSION SIZES

The tapered box gutter above the intrusion panel will always follow the tapered box gutter rules. However where the tapered box gutter meets the box beam, there are many variables to consider.

- The minimum size for the brick pillar is 300mm wide (wind post required).- The join must be minimum 150mm from the brick external face.- Brick pillar width less than 750mm in width, a wind post is required.

Before the beam is placed on the brick pillar they must be connected together with a fl at abutment bracket that spans the two beams. Use the fi xings provided to secure the plate in place as the plate will be inaccessible when the beam is in position over the brick pillar. NOTE: this is only used when a beam is joined on a brick pillar.

An alternative way of supporting a beam joint is the use of an aluminium support post placed under the beam joint. The post is cut into the existing brick work (if necessary) and fi xed to the concrete fl oor. A plate on top of the beam connects the two beams together. The plate sits in the cut out position of where the abutment bracket would sit. NOTE: fi rst beams are joined on the post fi xing plate then metal cleats are added later.

BOX GUTTER FOAM

The cavity wall brick must be cut to allow the post to sit 10mm from the external brick, this is packed off with box gutter foam to create a thermal break. A bigger void at the base must be cut into the wall to allow access to the fi xings at the base of the post

When converting an existing conservatory to an UltraRoof 380, it is important to accommodate for the previous box gutter positions on the conservatory roof when designing the UltraRoof replacement. When the old conservatory box gutter is removed, (either a 165 or a 265), the beam sits on the existing window frames lining up with the internal frame line datum points. This results in a special fi nishing detail for each case being used, as shown below.

CAVITY TRAY ASSESSMENT / VERTICAL DPC REQUIREMENT

APPROPRIATE FIXINGS

The correct selection/specifi cation of fi xings for UltraRoof380 is CRITICAL.

Ultraframe recommends HILTI chemical anchors where specifi ed and expanding anchors in other locations (to resist pull out forces).Using HILTI product codes/descriptions, use a HIT-V 80mm x M8 threaded anchor (stud*) fastened into a 10mm clean drill hole with gun injected mortar or adhesive capsules (with a minimum 80mm embedded) - always rigorously follow the manufacturers guidance www.hilti.com

In addition Ultraframe recommends the following alternatives; Fischer M8/M10 masonry injection anchor FIS V Rawl Fixings M8/M10 CFS RM50 or CFS RP30.

* Design load for each stud 2.5kN

It is good practice to undertake a risk assessment to determine IF cavity trays should be retro fi tted.

In zones 1 and 2, cavity tray installation

is based upon risk assessment -

factors include determining if elevation

faces prevailing wind, absorbancy of

brickwork and monitor joint type. Cavity

trays MUST be installed in severe/very

severe exposure zones (3 and 4).
